directly from Solo;
http://www.solo-performance.com/exhaustk.php, was $899 shipped, not the cheapest, but not the most expensive either. i felt it was the most reasonably priced one that sounded good. i found a couple other cat back for $500, but didn't look as well engineered, and didn't have sound clips with a V6. i am happy with it so far. if i would have went with an axle back, it would have been the MRT V2.
